The term "sign bit" has a very specific meaning which does not include the sign offset in an integer value. Floating point representation has a sign bit as do some DSP chips, most processors use 2s complement to represent signed numbers. This is neither semantics nor unimportant and drives me nuts ...

Well it seems that negative numbers are stored in signed integers using 2s compliment. Since fixed point numbers are just integers with a scale factor (for a x.y fixed point number the scale is the entire number / 2^y ) they work the same as integers with regards negative number storing. For a nibbl...

If sinLerp and other trig functions return signed values in 4.12, shouldn't one of those bits (the most signifigant bit usually isn't it) be the sign bit? So shouldn't it be 3.12 or 4.11 for a signed number?

I suppose that's logical. I'll stick to PCM format then.

In the MaxMod streaming example the actual sample data is derived from the function sinLerp() which returns a "4.12 fixed point number with the range [-1, 1]". This implies that the stream data format is also in 4.12 fixed format. My question is what is the format for raw sound data to be put in the...

Thanks a lot for help on this one. I've another problem though! I've only just tried to get this to work and I'm getting a linker error saying game.cpp:(.text+0x2): undefined reference to `fatInitDefault' Everything seems to be in order. Maybe I have to modify my makefile to link an extra library? A...

Ok, don't know what happened but I uninstalled devkit and reinstalled it, fixed it somehow.

Hi, I've been tinkering away at a program I'm writing and I haven't done a build in over a week. I tried to build my project and for some reason I'm getting this error: > "make" Makefile:9: /c/devkitPro/devkitARM/ds_rules: No such file or directory make: *** No rule to make target `/c/devkitPro/devk...
